Pi bonds

Pi bonds are a type of chemical bond formed between two atoms when their electron clouds overlap above and below the plane of their nuclei. They occur alongside a sigma bond (the primary bond) and involve the sideways overlap of p orbitals. Pi bonds provide additional strength and stability to molecules, especially in double and triple bonds. Unlike sigma bonds, pi bonds are more reactive because electrons are more exposed, influencing how molecules interact and react chemically. Overall, pi bonds are a fundamental component that help define the structure and reactivity of many organic compounds.
